Sea Sick Steve

I was lucky enough to catch Sea Sick Steve live on Sunday the 24th August. Dissapointed not to see John Paul Jones on bass - but I guess that was a temporary thing. How can a 73 year old man with three strings on his guitar make such a fantastic sound? I have to also say his drummer is really good - solid as hell. Loved it when the drummer used a broom to accompany Steve. Is that an original 50`s tweed Bassman that S.S.S. was using - sounded great - but it was one of three amps on stage so not sure what was coming out of where. Check this act out live if you can.
